Recent progress in nanotechnology has led to the development of spin-torque nano-oscillators (STNO), whose time constants, due to their nano-scale size, are naturally of the order of 1-100 nanoseconds. At SPINTEC we demonstrated experimentally for the first time that the use of such STNOs in swept-tuned microwave spectrum analyzers leads to a substantial reduction of […]

The European consortium SpintronicFactory, largely supported by the French laboratories Spintec (Grenoble) and the CNRS-Thales Joint Lab (Palaiseau), publishes in the journal Nature Electronics an ambitious roadmap for spintronics. This discipline on the borderline between magnetism and microelectronics is indeed reaching maturity, offering broad prospects for innovation. B. Dieny, I. L. Prejbeanu, K. Garello, P. […]

We present experimental evidence for coherent long-distance transport of angular momentum inside a non-magnetic dielectric via the coupling to circularly polarized sound waves that exceeds previous benchmarks set by magnon diffusion by orders of magnitude. The vision of spintronics is to use the spin of an electron rather than its charge to allow computers and […]

The SPINTEC laboratory in Grenoble, France, is seeking a PhD candidate for a joint application to a specific PhD studentship program. The joint application is to be submitted by March 2020 for a studentship available for admission in October 2020, for 3 years. Excellent academic record is mandatory. Applicants should have a Master’s degree in […]

We propose an original concept of spintronic memristor based on the angular variation of the tunnel magnetoresistance (TMR) of a nanopillar comprising several magnetic layers. We have experimentally developed the appropriate magnetic free layer and integrated it in a full nanosized magnetic tunnel junction pillar. In parallel, we developed a model describing the magnetization dynamics […]

In the field of spintronics, ferromagnetic/non-magnetic metallic multilayers are core building blocks for emerging technologies. Resonance experiments using stripline transducers are commonly used to characterize and engineer these stacks for applications. Here, we investigated the incompletely understood impact of eddy currents below the microwave magnetic skin-depth and explained the lineshape asymmetry and phase lags reported […]

Spin torque nano-oscillators (STNO) are nanoscale devices with wide band frequency tunability. Their multifunctional RF properties are well suited to define novel schemes for wireless communications that use basic protocols for data transmission such as amplitude, frequency and phase shift keying (ASK, FSK, PSK). In contrast to ASK and FSK, implementation of PSK is more […]
